 6. The metal sheetplate according to claim 5, wherein the slide rails extend upwards froma plane of the metal sheet plate.
 7. The metal sheet plate according toclaim 5, wherein the at least one punched hole is subdivided into twopunched holes separated by a connecting plate, wherein the two sliderails are formed at outermost opposite sides of the subdivided punchedholes.
 8. The metal sheet plate according to claim 5, further comprisingat least one tab element formed as an appendix of the metal sheet plateand extending inwardly within the at least one punched hole.
 9. Themetal sheet plate according to claim 8, wherein the tab element includesat least one receiving hole for a protruding element of the burner body.10. The metal sheet plate according to claim 8, wherein the tab elementincludes at least one support element formed as an appendix of the metalsheet plate and arranged opposite to the tab element.
 11. The metalsheet plate according to claim 5, further comprising at least oneelongated cut-out or slot for receiving and guiding a protruding elementof the burner body during a movement of said burner body, wherein alongitudinal axis of said elongated cut-out (30) or slot, respectively,extends parallel to the slide rails.
 12. The metal sheet plate accordingto claim 5, further comprising at least one tongue element formed withina further punched hole and extending parallel to the slide rails,wherein the at least one tongue element forms a snap-in mechanism withthe burner body.
 13. The metal sheet plate according to according toclaim 11, wherein the slot includes a widened hole at its one endportion and a shaped hole at its other end portion, wherein the widenedhole is provided for inserting the protruding element of the burnerbody, while the shaped hole is provided for engaging with saidprotruding element of the burner body.
 14. A domestic gas cooking hobcomprising the burner body according to claims 1, and a metal sheetplate comprising two opposing L-shaped slide rails formed therein, theslide rails being adapted to complementarily receive said lateral wingsof said burner body in order to fasten said burner body to said metalsheet plate.
 15. The domestic gas cooking hob according to claim 14,further comprising a pin element of the burner body and a tab elementassociated with a receiving hole of the metal sheet plate, said pinelement and said tab element with said receiving hole together forming asnap-in mechanism to affix said burner body to said metal sheet plate.16. The metal sheet plate according to claim 8, said tab element beinginclined downwards.
 17. The metal sheet plate according to claim 11,further comprising at least one tongue element formed within a furtherpunched hole and extending parallel to the slide rails, wherein the atleast one tongue element forms a snap-in mechanism with the burner body,and wherein the tongue element and the elongated cut-out are arrangedside by side.
 18. A domestic gas cooking hob comprising: a gas burnerhaving a burner body with a base plate comprising a pair of lateralwings opposing and extending parallel to one another at a lower portionof the burner body; a metal sheet plate adapted to support the gasburner and comprising a pair of spaced slide rails opposing andextending parallel to one another, said slide rails being formed as tapspunched in the sheet metal plate so that they extend above an uppersurface of the sheet metal plate, said slide rails being spaced apartfrom one another so as to slidingly accommodate therebetween the baseplate of said burner body, including said pair of lateral wings thereof,along a sliding axis parallel to the slide rails, wherein said sliderails further are shaped to complementarily engage the respectiveopposing wings of said base plate so as to permit sliding thereof alongsaid sliding axis but to inhibit movement thereof transverse to saidsliding axis; wherein upon translating said gas burner horizontallyalong said sliding axis with said opposing wings of the base plateengaged with the opposing slide rails of the metal sheet plate, said gasburner and said metal sheet plate are configured to achieve a snap-fitconnection therebetween that inhibits further horizontal translationalong said sliding in either direction, thereby fixing said gas burnerto said metal sheet plate.
 19. The domestic gas cooking hob according toclaim 18, said burner body further comprising a pin protruding downward,said metal sheet plate comprising a hole adapted to accommodate saidpin, wherein said pin and said hole interact to provide said snap-fitconnection.
 20. The domestic gas cooking hob according to claim 18, saidhold being provided in a deflectable tab or tongue formed as anappendage of said metal sheet plate and extending within a punchedopening in the metal sheet plate, the hole being formed in said tab ortongue, the pin adapted to slide over and thereby deflect said tab ortongue upon translation of the burner body along said sliding axis untilsaid pin reaches and is accommodated within said hole to therebyestablish said snap-fit connection.
